Isolate Temperature And Conductivity; Isolate 'Out Of Bypass' Circuit - Fresenius Medical Care 2008T Troubleshooting Manual

F- 2.9.2 ISOLATE TEMPERATURE AND CONDUCTIVITY
ENSURE NO HYDRAULIC LEAKS BEFORE CONTINUING!
a)
b) Call the Home screen. Is [Temperature] REMAINING between 35.5 and 38.5 °C AND Conductivity
REMAINING between 13.0 and 14.5 mS? TWO (2) possible scenarios:
1) IF (and ONLY if) Temperature AND / OR Conductivity is
page 47
to , procedure number
2) IF Temperature AND Conductivity in range: See parts a THROUGH f below:
a) At the bottom of the screen, press the 'Dialysate' tab.
b) If necessary, adjust the Conductivity Limits until the
'Actual' Conductivity is CENTERED between them
(Figure right).
c) Press 'Enter'
d) Allow three (3) minutes OR until if the Conductivity
window remains white!
e) Call debug screen 0 (Figure right) and locate Valve #24's
'dot'. At this point it should be white.
f) See procedure number
F- 2.9.4 ISOLATE 'OUT OF BYPASS' CIRCUIT
CLOSE THE SHUNT DOOR COMPLETELY!
a)
b) Figure right, from here forward, if (and ONLY if) a "Dial
Valve Failure" OR "Act Byp Valve Fail" banner appears
page 711
proceed to
c) Is Valve #24's 'dot' BLUE?
Yes BLUE! See procedure number
No WHITE! See parts a THROUGH d below:
a) ENSURING the shunt door is closed, call debug screen 2.
b) ENSURE CVRCLS (2
c) Return to debug screen 0.
d) Allow up to three (3) minutes OR until if Valve #24's 'dot' turns blue. TWO (2) possible
scenarios next page:
